My first post here so hello to you all. I have a vizio tv that had the screen go black. Bought both boards online and replaced. No luck. Using the flashlight test i can see the image and the sound is there. The voltage leaving the power board and going to the led strips (while using original power board and other one i bought) is 68-69 volts dc. I read it needs to be around 100 to make the leds work. I tool out the led strips and tested them individually with 3vdc and i have one bad on 3 different strips. My model number is LATKOCBP. Can i buy the leds or replacement strips? Are both of my power boards bad since i get 68-69 vdc regardell if leds are plugged in or not? Any help would be great at this point. I found replacement strips but not with my serial number. Does it matter? They are also 6916L-1174A, 75A, 76A and 77A. I am an electrician but i have little experience with electronics.
